Hydraulic Centrifuge and Screw Pump: A Match Made for Wastewater Treatment.

Hydraulic centrifuges and screw pumps are two types of equipment that are often used together in industrial applications. The hydraulic centrifuge is used to separate solids from liquids, while the screw pump is used as the feeding pump for the centrifuge.

GN Solids Control is a leading manufacturer of decanters centrifuges. We have partnered with Viscotherm and ROTODIFF®, leading brands of centrifuge hydraulic driving systems from Switzerland, to develop the Full Hydraulic Drive (FHD) Centrifuge. This centrifuge meets the highest standards and is designed for international clients. The FHD Centrifuge uses a hydraulic bowl and scroll drive system that is powered by a hydraulic pump unit. This system drives both the hydraulic motor ROTODIFF and the bowl of the centrifuge. The two hydraulic oil circuits allow for independent, stepless, and large-range speed regulation for the bowl and conveying. The FHD Centrifuge has several advantages. It can be used in high-temperature ambients, is designed for heavy mud, and has a flexible bowl and differential speed. The compact one-skid design makes it easy to rig up.

A screw pump is a progressive cavity pump that uses a rotating rotor with a series of helical blades to move fluids. The blades create a series of chambers that trap the fluid and move it along the pump. The pump is gentle on the fluid, so it does not shear or agitate it. It can handle high-viscosity fluids and hard-suspended particles for a mud system, and a good feeding pump for centrifuges. It is easy to maintain, better pumping than a centrifugal pump, and the only worn parts are the rotor and stator.

The combination of the centrifuge and the screw pump could be mounted with a skid:

If you are interested in the skid and equipment, or you have a project in drilling mud treatment or waste fluid treatment, please feel free to contact me for more details.

Liquid Mud Plant: A Key Piece of Equipment for Drilling Operations

Drilling is a complex and dangerous opeLiquid mud plants are one of the most important pieces of equipment in a drilling operation. They are used to produce and circulate drilling mud, which is a fluid that is used to lubricate the drill bit, remove cuttings from the borehole, and control formation pressure.

Last Tuesday, I received an inquiry from a customer about our liquid mud plants. I replied with some pictures of our tank system, which is a part of a mud plant. However, the customer needs more details.

2023.06.29 Solids Control System

The liquid mud plant typically consists of storage tanks (usually cylinder tanks)with a mud system, but the system is not all the same as a solids control system. A mud plant tank system including the following equipment: The Hopper with Agitators, centrifugal pumps,  Shale shaker (as well as mud cleaner), and sometimes centrifuges are also necessary.

 

The agitator mix the drilling mud ingredients together, such as barite added from the hopper. GN supplies two types of mud mixers that are useful in a tank system: jet mud hopper and shear hoppers.

The shale shaker separates the drilling mud from the cuttings. GN typically recommends the GNZS-594 for mud separation. In addition, a shaker can be installed with desanders and desilters to create a mud cleaner. GN supplies 2S12N or 3S16N mud cleaners with 594 bottom shakers.

The centrifuge removes very fine particles from the drilling mud. The specific model of centrifuge will vary depending on the specific requirements. Usually, we supply 363, 453 and 553 models.

The centrifugal pump moves the drilling mud or barite through the separation equipment and hopper or pumps the mud to the storage tanks. All the spares of GN C-pumps are replacement with Magnum pumps.

Besides, a complex mud plant might need degassers or screw augers for degassing or screw muds. A vertical cutting dryer is necessary when treating OBM.

A liquid mud plant is essential for safe and efficient drilling operations. The mud must be mixed to the correct specifications, and it must be circulated through the drill bit at the correct rate. The cuttings must also be removed from the mud on a regular basis.

I hope this blog post has been helpful in providing you with an overview of liquid mud plants. And I had already shared with my clients the brochure of the mud system and equipment introduction. If you also have an inquiry of a mud plant, please contact me at samuel@gnsolidscontrol.co.
